Fig.3-2 ： Solenoid valve installation procedures (RH-12FRH/20FRH)
The installation procedure is detailed below.
1) Remove the screws fixing the No. 2 arm cover U, and remove the No. 2 arm cover U.
2) Fix the solenoid valve to the plate in the position indicated in
. Place it so that the solenoid valve's
primary piping connection joints (P, R ports) are located on the upper side, and fix it securely using the M4
screws included (tightening torque: 1.39 to 1.89N ・ m).
3) Connect the connector (GR1, GR2) of solenoid valve with connector of robot arm side (GR1, GR2). Connect
with the same names. The hand output signal cables of the robot arm side are located close to where the
solenoid valve is installed and are tied up with cable tie. Pull out and connect them to the connectors. Fix
the connectors so that they will not move along with the robot movement. (Refer to
tor protection when the option devices are installed"
4) Connect the primary piping air hose (φ6). The air hoses are located close to where the solenoid valve is
installed and are tied up with cable tie. Cut the cable tie and connect them. Of the two air hoses, connect
the one marked “AIR IN” to the solenoid valve's P port, and the one marked “RETURN” to the R port.
Note) When connecting the RETURN air hose, be sure to remove the dust cap attached at the RETURN
joint on the robot base section. If the cap is not removed, exhaust air pressure will increase and
the solenoid valve may not operate properly.By connecting the exhaust air hose (φ6: customer
